Values are n or n (%) unless otherwise indicated. Each interior cell contains the numbers of persons in the corresponding risk categories under the original PCE and HRQoL in addition to PCE.
ASCVD= Atherosclerotic cardiovascular disease; HRQoL= Health related quality of life; PCE= Pooled Cohort Equations; NRI= net reclassification improvement.
